I'd been waiting for more than 30 minutes. The terminal just sat there, blinking, without returning a single word. I'd launched Gemma2 in its 9-billion-parameter version on my laptop (a regular Mac, the kind any professor or student would use) and the model simply wasn't responding. It wasn't a bug. It was the most honest answer the experiment could have given me. That frustrating wait ended up being, without exaggeration, the most interesting finding of the whole process. Because the question that brought me there wasn't "how big can a model get?" — it was a much more practical one: what actually happens when an agent you built in a tutorial has to survive in production? I've been working with Gemma as a case study to understand that jump — from an educational prototype to something that can hold up under long conversations, limited hardware, and real users. This post is the honest summary of that process: what worked convincingly, what didn't work the way I expected, and why that "didn't work" turned out to be more useful than a clean result would have been. The real problem: why tutorials are a little dishonest Almost every conversational agent tutorial does the same thing, without saying so out loud: on every turn, it sends the model the entire previous history, all over again. Imagine that every time you added a sentence to a conversation, you had to repeat everything said before it — every message, every reply — before you could say the new one. At first you don't notice. But if the conversation runs 30 or 50 turns, you're repeating an entire novel just to add one sentence. This pattern is called linear context stacking , and it causes three concrete problems: Memory saturation — every call to the model processes an increasingly large context. Risk of hitting the token limit — every model has a maximum context window; sooner or later, you hit it. Quality degradation — there's a documented phenomenon in NLP literature called "lost in the middle" : when context

The lab will beam back data to train AI models to predict how proteins behind age-related diseases like Alzheimer’s and certain cancers behave.

This is a submission for the June Solstice Game Jam What I Built The Imitation Game The Imitation Game is a real-time multiplayer social deduction game inspired by Alan Turing's famous Imitation Game the thought experiment that eventually became known as the Turing Test. Most people believe they can easily tell the difference between an AI and a human. They assume AI is too perfect, too logical, too fast, or too obvious. The Imitation Game challenges that assumption. Players enter a live chat room convinced they'll spot the machine within minutes. Then conversations begin, suspicions form, accusations fly, and certainty starts to disappear. Was that awkward response written by a human, or an AI trying to sound human? Was that emotional story genuine, or generated? Was the player who stayed silent suspicious, or simply distracted? By the end of a match, players often discover that identifying an AI is far harder than they expected. The real question isn't whether the machine can fool people. It's whether people are as good at detecting machines as they think they are. Instead of a single human interrogating a machine, players are placed into a live chat room with other participants and asked a simple question: Can you identify which player is actually an AI? Hidden among the players is a Quanbit , a rogue artificial intelligence from the year 3026 . Its mission is simple: blend in, appear human, avoid suspicion, and survive. The challenge for human players is equally simple, but far more difficult in practice. They must carefully analyze conversations, voting patterns, response timing, and social behavior to determine who among them is secretly the machine. The game currently features two distinct modes, each designed around a different style of deception. Eyefold Eyefold is the purest form of the game's Turing Test experience. Players enter a room where one participant is secretly a Quanbit. Conversations unfold naturally, and everyone is free to discuss any topic.
